Attention holiday shoppers: the marathon to Christmas begins now! Soldier up and step into your shopping gear – it’s a war out there. You’ll need a light, convenient bag to make the heft of all your purchases a little less daunting. Marni’s cross body ($1,760) with a zippered outer pocket (for credit card safety and access) and fierce studs will help you through battle. Forget fancy footwear! You have no idea how long you’ll be running around, so comfort is key. Short of actual running shoes (only cute on a treadmill), classic Converse ($60) will keep you moving at optimal speed. And if you’re like me and shop for yourself as much as for others, you’ll need to wear dressing room-ready pieces that are easy to slip in and out of like a simple J. Crew tee ($29) and T by Alexander Wang stretch pants ($245). Now slide on Vanessa Bruno Athé’s biker jacket ($660) to ward off the chills and head to the starting line. Ready, set go! Available on Net-a-Porter.
